I iinherited my father in laws old target .38 from when he used to shoot bullseye competition. He purchased it from Gil Hebard back in the early 60s. It's a Colt Officers Match that was a factory conversion to "short action"..Right now it only functions as single action. If I try to use it double action the hammer is not cocked to firing position. It's not a problem for me but I'd like to know from anyone familiar with this conversion if it's only meant to operate as single action. Seems to me that would slow things down for the rapid fire part of bullseye competition.
